Title: Electrical connectors
Inventor: TWEEDLE ROBERT JACK
IPC: H01R13/64
Filed: 1965-04-14
Abstract: 1,112,046. Two-part coupling. HAWKER SIDDELEY DYNAMICS Ltd. 25 May, 1966 [14 April, 1965], No. 16035/65. Heading H2E. Insulating block 2 carries male or female electrical contact elements (not shown), extending through it from its front 3, 7 to its rear 4, 8, and is surrounded by a casing in two parts. The front part 15, 16, 17 of the casing is hand-rotatable with respect to the block 2 on bearings 22, 26, which are attached to panel 1 or to a separate mounting element (63), (Fig. 5, not shown), and spring-loaded ballbearing 54 co-operates with cavities 55 to click-stop its rotation at spaced positions. Key-ways 58 in rotatable casing 15 ensure that engagement with another connector (not shown) can take place at one relative position of their casings only (the other connector having a casing and contact-carrying block which are relatively rotatable). If, for example, each connector has six possible predetermined angular positions of its rotatable casing and contactcarrying block, rotation of the casing part 15 makes it possible for the connector to receive the other when it is in any of its positions.

Patent GB-1046774-A (GB)
Title: Improvements in ultrasonic flaw detection equipment
Inventor: BATES EDWARD ARTHUR BENJAMIN
IPC: G01N29/265
Filed: 1962-04-27
Abstract: 1,046,774. Ultrasonic testing. GLASS DEVELOPMENTS Ltd. April 26, 1963 [April 27, 1962], No. 16197/62. Heading H4D. In an ultrasonic flaw detection arrangement in which the test object is scanned by movement of a probe the probe is supported by a carriage which moves to impart one component of scan, the other component of which is effected by moving the probe with respect to the carriage. Figs. 1 and 2 show one embodiment in which the test object comprising a plate 15 supported in a water-filled tank 10 (which may be drained by sluices 11) is scanned by an ultrasonic test probe 25 which oscillates to-and-fro in a slot 24 provided in a plate 22, the latter, together with the portion 17 forming a gantry which is moved parallel to the longer dimension of the plate 15 along track 18. The electrical conductors supplying the probe are supported by a carrier 26 and pass to a cable trough 27 running the whole length of the tank. The scanning motion may be produced by electric motor means or by manual means. In the case of the former an electric motor 33 (see Fig. 2) operating via a speed-control device 34 (adjustable by means 35) effects continuous movement of endless chains 44 which are coupled to the probe carriage 45 such that the latter oscillates backwards-andforwards to produce one component of scan, the other of which is effected in pinion 20 coacting with a rack 19 adjacent track 18. For manual operation the two components of scan are effected by means of control elements 48, 49, respectively. The gantry also carries a recorder 28 the motion of the stylus of which may be effected by coupling it to the probe carriage 45 by means of a chain whilst the motion of the recording paper 29 is produced by movement of the gantry. The latter, additionally, carries a cathode-ray tube indicator 30 producing an A or B scan (or both types of presentation) and an alarm unit 31 to stop the control mechanism or detection of a flaw and warns the operator. In a second embodiment the probe 25 (Fig. 3) counterbalanced at 59, is rotated about a vertical axis by means of a tube 52, gear drive 53 and motor 54 and to avoid the use of slip-rings the probe is prevented from rotating about its own axis by means of a chain 62 coacting with a sprocket 63 attached to the probe support 58 and with a sprocket 61 fixed to the fixed tube 55. In the operation of this embodiment the assembly as a whole moves to produce the other scan component. When, as shown, a single probe is employed readings are only taken during alternate half-revolutions. Two probes, one at each end of arm 57, may be employed, however, and readings again taken during alternate half-revolutions.

Title: Method for improving the static properties of acrylic polymer fiber
Inventor: BURNTHALL EDWARD VERNON
IPC: D06M23/00
Filed: 1958-05-21
Abstract: The anti-static efficiency of anti-static agents when applied to acrylic polymer fibres containing at least 80% by weight of acrylonitrile in polymeric form and yarns and fabrics containing the same is improved by applying the anti-static agent from an aqueous bath containing a buffering agent resulting in a final pH of 6.5-9 over a period of time of not less than 5 minutes at an elevated temperature.  The fibres may be made from polyacrylonitrile or copolymers or terpolymers containing at least 80% by weight of acrylonitrile plus one or more monoolefinic monomers copolymerizable therewith, e.g. acrylic and methacrylic acids, vinyl esters of monocarboxylic acids having up to four carbon atoms, alkyl acrylates and methacrylates having up to four carbon atoms in the alkyl groups, dialkyl fumarates, maleates and crotonates having up to four carbon atoms in the alkyl groups, styrene, alphamethyl styrene and other alkenyl-substituted hydrocarbons, alkenyl esters of halo substituted carboxylic acids, vinylidene halides, methacrylonitrile and tertiary N-heterocyclic alkenyl-substituted compounds such as vinyl pyridine, vinyl pyrrolidone, alkenyl pyrazines and alkenyl imidazoles and benzimidazoles, or from blended polymers and copolymers containing at least 80% by weight of acrylonitrile.  The anti-static agent may be a cationic, anionic or nonionic agent, e.g. complex amines, quaternary ammonium compounds, fatty acid amines, substituted fatty amides, substituted imidiazolines, alkyl polyoxy alkylene amines, fatty alcohol sulphates, fatty acid salts of carbamates, salts of alkyl phosphorus acids, complex amino polyglycol fatty acid derivatives, alcohol phosphates, polyesters of aliphatic glycols with dicarboxylic acids, polyoxy alkylene fatty alcohols, poly alkylene glycols, polyoxyethylated vegetable oils, ethylene oxide condensates with higher fatty acids, copolymers of ethylene and propylene oxides and higher alcohol fatty acid esters.  Suitable buffering agents are mixtures of tetrasodium pyrophosphate and hydrochloric acid, disodium hydrogen phosphate, mixtures of disodium hydrogen phosphate and sodium dihydrogen phosphate, sodium carbonate, sodium bicarbonate and urea.  The fibres are preferably treated with the aqueous bath at 160 DEG -212 DEG F. for 5-30 minutes after they have been dyed.  Fibres may be treated before or after they have been made into woven or tufted carpets.  The Provisional Specification refers to the application of anti-static agents to acrylic fibres from baths buffered to a pH value of 5 to 9 at a temperature not less than 160 DEG F.

Title: Improvements in hydraulic absorption apparatus for the generation of heat
IPC: F22D11/00
Filed: 1927-06-23
Abstract: 297,158. Heenan & Froude, Ltd., and Walker, G. H. June 23, 1927. Heating by friction.-A hydraulic absorption apparatus for the generation of heat comprises the combination with a hydraulic absorption apparatus of a heat accumulator, the steam space in which is connected with the interior of the hydraulic absorption apparatus at a point or points at or near the centre of the vortex or vortices set up therein, where under running conditions the pressure is relatively low. A heat generator A comprising a hydraulic brake similar to that described in Specification 24949/10, [Class 106 (ii), Dynamometers &c.], has a rotor B on a shaft B' driven from a prime mover. Passages c formed in the vanes of the stator C connect the points corresponding to the centres of the vortices with annular spaces c and these are connected through a valve d by a pipe D to the steam space c of an accumulator E. Passages c<2> formed in the vanes, of the stator connect the water spaces between the vanes with annular spaces c<3> and water inlets F<1> terminating in a single pipe F. The water outlet pipe G is connected to the annular space B<2> surrounding the rotor. The pipes F, G are connected to the water space of the accumulator through a distributing valve H controlled through a. rod from a governor (not. shown). Thus when the inlet is wide open and outlet almost closed the power absorbing elements are packed full of water and the power consumed is a maximum and when the inlet is nearly closed and the outlet wide open, the power consumed is a minimum. A circulating passage J is preferably employed so that the pressure of the water supplied through the pipe F may be in excess of the pressure head between the level of the water in the accumulator E and the pressure in the device A. Suitable isolating valves f, g are arranged between the device A and the distributing valve H, valves j, j<1> between the valve H and the pump J, valves e<2>, e<3> between the valve H and the accumulator E, and a valve d in the pipe I). The distributing valve H comprises four pistons mounted in the rod K and adapted to control six parts h<1> - - h<6>. In a modification, two butterfly valves are employed one in the pipe F and the other in the pipe G and there are connected to the rod the valve H being dispensed with.

Title: Improved process and apparatus for deodorizing and sterilizing air
IPC: F24F8/26
Filed: 1956-05-30
Abstract: 792,033. Air deodorizing and sterilizing processes and apparatus. BRUZZONE, G. May 30, 1956, No. 16724/56. Class 81 (1). In a process for deodorizing and sterilizing the air of rooms &c. a slow, hot and preferably rising, moistened air current is produced to which ozone is intimately mixed, and to a large extent dissolved in the water vapour, to produce hydrogen peroxide, which in turn produces nascent oxygen. As shown in Fig. 1, the apparatus used comprises a container for water, means 7 to heat the water, an ozone generating device 11, an annular container provided with openings 5 communicating with the ambient air and placed at different levels, heating means arranged within the container to create a slow rising air current, the water vapour produced by the water heated in the container and the rising air current, and the ozone converge at a point in the container in such a way as to form at the exit of the container itself, a rising current of air which is moistened by water vapour and hydrogen peroxide vapour. In another modification shown in Fig. 3, the apparatus is formed of an elongated shape envelope, open at the ends and including a centre portion 16 serving as a tank to contain water, the flow of which is controlled by a float 20 and headed by electric element 21 thermostatically controlled and two end portions 17, 18, the former containing an ozonizing member 23 and an air blower 24 and the latter having a small rim formed at the end, which holds the droplets formed during the operation and which are returned to the container 16, by flowing along the slightly inclined bottom of the portion 18. Air is forced by the blower 24 against the ozonizing members 23, takes up ozone and is deflected by a diaphragm 26, arranged in the container 16, towards the heated water in the bottom portion of the container so mixing the ozonized air with the water vapours producing a current of air rich in hydrogen peroxide vapour which is discharged at the end portion 18.
